Description

MHO retaining rings are axially assembled internal ANSI metric circlips and are part of Rotor Clip’s tapered section retaining ring line. Once installed into the groove of a housing/bore, the portion of the ring protruding from the groove acts as a shoulder to securely hold an assembly in place by preventing axial movement along the bore.
